Knot

Knot is a 3D Celtic Knot generation and rendering application for exploring different types of randomly generated knots. Most Celtic knots are only sort of 3D, in that they only use the third dimension for weaving the string, but otherwise exist on a plane. Knot will allow you to render these 2D Celtic knots in 3D. However, it also allows you to generalise these knots to create 3D Celtic knots rendered in 3D.

If you'd like to play around with some 2D knots before downloading the application, you can try out my Celtic Knot Web App. You can also read about the reasons why this application was created in the first place.

For bug reporting, discussion forums and other useful tools see the Knot project pages on SourceForge.

About a week ago SourceForge suffered what seemed to be a catastrophic outage, taking everything offline. I realised when some of the tools I use for continuous integration and syndication started to complain at me. I'm pleased to see things are getting back to normal. Both Functy and Knot3D are hosted on SourceForge and both are now back online. SourceForge is an important site from an Open Source perspective and I feel for the SourceForge team who clearly have had to do a lot of work to piece everything back together.

Now sporting its new name, along with a bundle of bug fixes, a new version of Knot3D is now available. Knot3D is an open source (MIT-licensed) Celtic knot rendering program. As well as traditional flat knots it'll also create full three-dimensional cuboid knots, which can be output as mesh files for rendering or 3D printing. Installers are available for Linux and Windows (as well as the sourcecode if you're using something else).

Knot now has a new name: it's now called knot3d. It's not a massive change, but an important one since it turns out there's already a (very different) Debian package called knot. The new name is to avoid it clashing. Thanks to Daniel Matthews for highlighting the issue!

Knot3DVersion 0 (1 Jul 2013) for Linux and Windows.Knot3D is an open source Celtic knot rendering application. It'll render standard knots on a 2D plane with a 3D weave. It also generalises these to allow proper 3D knots to be rendered. More info...Download: binary, source, screenshot.
